Woven Mesh Filter Cartridges

Woven mesh filter cartridges are mostly used to filter gas and are called air woven mesh filter cartridges (hereinafter referred to as woven mesh filter cartridges).

A woven mesh filter cartridge is a surface filter element, which uses the tiny air-permeable tissue formed on the surface of the filter material to block the particulate matter in the gas.

A woven mesh filter cartridge is a commonly used dust-catching device. It has the characteristics of a high catching rate, low resistance, and easy to put into the flue for sampling. It is widely used in particulate matter, catering industry oil fume, asphalt fume, chromic acid mist, sulfuric acid mist, and another pollution物 sampling. According to the material, it can be divided into two types: glass fiber is woven mesh filter cartridge and corundum woven mesh filter cartridge. The most widely used one is the glass fiber woven mesh filter cartridge. The glass fiber woven mesh filter cartridge is made of ultra-fine glass fiber, and the trapping rate of dust particles above 0.5μm can reach more than 99.9%.

The installation method of the woven mesh filter cartridge is divided into vertical hoisting, oblique installation at a specific angle, flange installation, and so on.

Features

1. Greatly increase the effective filtration area;

2. Ensure a low and stable pressure difference and increase air flow;

3. The element of the woven mesh filter cartridge is small and easy to install;

4. Especially suitable for industries with high dust concentration.

The commonly used automatic cleaning methods for woven mesh filter cartridges include high-pressure gas pulse back-blowing and mechanical vibration. Pulse blowback uses the parameters preset by the controller to give a signal to the solenoid valve, which instantly opens and closes the solenoid valve diaphragm to allow high-pressure gas to enter the blowing pipe, and uses the rapid expansion force of the gas to shake off the dust on the surface of the woven mesh filter cartridge. We set the gas pressure to about 6 kgf. Mechanical vibration dust removal is often used in small single-machine woven mesh filter cartridge dust collectors. It uses the shaking force generated by the eccentric device on the flower plate of the dust collector to clean dust. This action needs to be shut down and operated.

Woven mesh filter cartridge dust collector has appeared in Japan and some countries in Europe and America as early as the 1970s. It has the advantages of small size, high efficiency, low investment, easy maintenance, etc., but because of its small equipment capacity, it is difficult to combine into a large air volume. The equipment has a low filtration wind speed and a narrow application range. It is only used in industries such as grain and welding, so it has not been widely promoted for many years. In recent years, with the continuous development of new technologies and new materials, companies in Japan and the United States have improved the structure and filter material of the dust collector, making the woven mesh filter cartridge dust collector widely used in cement, steel, Electricity, food, metallurgy, chemical industry and other industrial fields, the overall capacity has increased several times to become a large-scale dust collector (GB6719-86 category) with a filtration area of >2000m2, which is a solution to the traditional dust collector’s difficulty in collecting ultra-fine dust, high filtration wind speed, and dust removal The best solution for poor effect, easy wear and tear of the filter bag, and high operating cost. Compared with the existing bag-type and electrostatic precipitators on the market, it has a large effective filter area, low-pressure difference, low emission, small volume, and use. Long life and other characteristics have become a new direction for the development of industrial dust collectors.

The woven mesh filter cartridge dust collector is composed of a woven mesh filter cartridge as a filter element or a dust collector using pulse blowing. The woven mesh filter cartridge dust collector can be divided into oblique insertion type, side-mounted type, hoisting type, and top-mounted type according to the installation method. Woven mesh filter cartridge dust collector is divided into woven mesh filter cartridge materials, which can be divided into long fiber polyester woven mesh filter cartridge dust collector, composite fiber is woven mesh filter cartridge dust collector, anti-static woven mesh filter cartridge dust collector, and flame retardant woven mesh Filter cartridge dust collector, coated woven mesh filter cartridge dust collector, nano woven mesh filter cartridge dust collector, etc.
